Question

Thymidine
A.can participate in hydrophobic interactions due to its methyl group
B. is replaced by uracil in RNA
C. normally forms two hydrogen bonds with adenosine
D. all of the above

Answer 1

Hola mate !! ✌️✌️

here's your answer...⬇️⬇️

Thymidine is a nitrogen base which is found in DNA but is replaced by Uracil in RNA . It has a methyl group and forms 2 hydrogen bonds with Adenosine .

✔️So your answer is... D.

hope it helps ! ❤️❤️

Answer 2

Concept:

Thymidine.

Explanation:

Thymidine:

Thymidine is a pyrimidine Deoxynucleoside that is also known as deoxythymidine, Deoxyribosylthymine, or thymine deoxyriboside. Deoxythymidine is the DNA nucleoside T that, in double-stranded DNA, combines with deoxyadenosine (A). It is utilised in cell biology to synchronise cells in the G1/early S phase. Because there are no thymine nucleotide precursors involved in RNA production, the prefix deoxy- is frequently omitted.

Prior to the increase in thymidine use driven by the requirement for thymidine in the creation of the antiviral medication azidothymidine (AZT), herring sperm supplied the majority of the world's thymidine. Thymidine is found nearly entirely in DNA, however it is also found in the T-loop of tRNA.

• Deoxythymidine is a nucleoside made up of deoxyribose (a pentose sugar) linked to the pyrimidine base thymine.

• Deoxythymidine can be phosphorylated with one, two, or three phosphoric acid groups to produce dTMP, dTDP, or dTTP (for the di- and tri- phosphates, respectively).

• Deoxythymidine is a non-toxic chemical that occurs naturally in all living creatures and DNA viruses as one of the four nucleosides in DNA. Uridine replaces thymidine in RNA (uracil joined to ribose).

Answer:

Option (d) all of the above.
